EXHAUST-SILENCEB.

Specication of Letters Patent.

Patented June 25, 1912.

Application led January 27, 1912. Serial No. 673,791.

To all wwm i may concern:

Be it known that It, ZACHABIAH SWEARIN- een, a citizen of the United States, residing atUsceola, in thecounty of Clarke and State of iowa, have invented certain new and useful lmprm-'ements in Exhaust-Silencers, of which the following is a specification, reference being had to the accompanying drawmcs.

illy invention relates to new and useful improvements in exhaust silencers, known particularly to those working in the art as mufflers and my object is to provide a device of this character which may be readily applied to use in connection with the exhaust pipe of explosive engines to suppress the noise of the escaping gases and products of combustion.

A further object of the invention resides in providing a device of this character which will have a maximum cooling eect upon the exhausting gases and a still further object resides in providing a device which is so constructed as to prevent back pressure from affecting the power of the engine.

Another object of my inventionresides in providing a device which issimple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

TWith these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

l'n the accompanying drawings forming a part of this application, Figure l is a vertical longitudinal section through the device and Fig. 2 is a horizontal section therethrough as seen on line 2--2 of Fig. l.

ln carrying out my invention l shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which- 1 indicates a housing, preferably of cylindrical design, the heads or end walls 2 and 3 of which have respectively threaded in engagement therewith the conduits or pipes 4 and 5 said pipes forming the inlet and outlet ports, respectively, of the device. These heads or end walls 2 and 3 are removably mounted on the housing or cylinder l by means of the bolts or shafts 6 which extend longitudinally through said housing and have the ends thereof threaded to receive the nuts 7, whereby'said heads will be securely held to the housing. l

As stated, the conduit or pipe l forms the inlet portfor the exhaust to the housing l and disposed in the housing l is a cone shaped deflector 8, the apex of which is positioned immediately adjacent the entrance ofthe port et to the housing, said defiector being hollow and provided with a .peripheral flange 9 at the flaring edge thereof. ln order` to securely mount the deflector in the housing, to permit a space to intervene between the flaring end of the same and the inner wall of the housing, the bolts 6 are disposed through openings in the ange 9 thereof and nuts 10 are engaged with threaded portions of said bolts or shafts 6 above and below said flange 9. An-additional defiectpr plate 1l is provided, the saine being circular in design to allow the periphery thereof to snugly fit the inner periphery of the housing and said plate is also held to the bolts or shafts 6, which extend therethrough, by means of nuts 12 vwhich engage additional threaded portions of the bolts and contact with the upper and lower faces of the plate. Said plate is provided with a central restricted opening 13 whereby the products of combustion after passing through the space left between the deiector 8 and the wall of the housing l may unite and pass therethrough and an additional defiector plate la is provided beyond the plate 1l. This plate lllis of concaveconvex design, the convex portion thereof facing the plate 11 and the same is held to the bolts or shafts 6 by means of the nuts l5, in a inanner similar to the manner in which the deectors 8 and il are secured thereto. rlhis plate le, however, is of a diameter substantially equal to the diameter of the flaring end of the deflector 8, thereby providing a space between the peripheral edge of .the same and the inner wall of the housing to permit the products of combustion, after passing through the openings 18 in the plate l1, to be separated and pass therearound to the outlet port 5.

ln practice, it will be seen that this device may be readily applied to the exhaust pipe of an explosive engine and as the exhaust enters the housing 1 through the pipe'fl, the same will be broken or separated to cause the-products of combustion to pass around the cone-like deflect-or 8 and through the space between the flaring end of said delos Hector. and the Wall of said housing. After passing through the space mentioned, the

'products will have a tendency to unite to ing 13 1n the plate 11, the products of combustion will strike against the convex plate 14 where the same will again be caused to separate in order to pass therebeyond, the same passing through the space between the peripheral edge4 of said plate andthe inner WallI of the housing vto unite therebeyond and pass through the outlet pipe 5. By the time the productsof combustlon reach the outlet pipe, it will be appreciated that the same will be cooled to a considerable extent and that the sound incident to t-he explosion will be suppressed. It will also be appreciated that in` view of the fact that there are no minute openings through which the products are to pass, there will beno clogging of the same to prevent the effective operation of the device, but should it be desired, at any time, to remove the deflector plates rfor cleaning purposes, it will be seen that it' is only necessary to remove the nuts at the one end of the bolts or shafts 6 whereupon the opposite head or end wall of `the housing together with the bolts and division or deiiector plates thereon may lbe readily removed. Should it be found necessary, at any time whatsoever, to remove any of the deflectors 8, l1 or 14 the same may be readily accomplished by merely removing the nuts which secure the same to the bolts or shafts 6 and thus it will be appreciated that little or no trouble'will be experienced in either setting up the device or taking the same down for cleaning purposes. Furthermore, it will be seen that the back pressure incident to most muiers or exhaust silencer's of this type will not materially aect the u will be eliminated.

From the foregoing it will be seen that I have provided a simple, inexpensive and eiiicient means for -carrying out/'the objects of my invention, but while I have particularly described the elements most well adapted to perform the functions set forth it is obviousthat various changes in form, proportion and in the minor details of construction may be resorted to without departing fromthe spirit or sacrificing any ofthe principles of the invention. y

Having thus described my invention what I claim is:

1. A muiiler comprising a cylindrical member having removable heads thereon, said heads being provided respectively with inlet and outlet ports, tie rods extending through said cylinder to secure the heads in position thereon, a substantially conical deflector member carried Within the cylinder, the apex of said member being disposed immediately adjacent the inlet port of the cylinder, a pair of additional deflector plates wit-hin said cylinder, one of said plates hav- 'ing the peripheral edge thereof contact-ing with the inner wall of the cylinder and provided with a central opening, the other plate `Stb-.

being of concavo con'vex deslgn, and means to removably secure all of said defiector members to the tie rods.

2. A mullier comprising a cylindrical member having removable heads thereon, 35 said heads being provided respectively with inlet and outlet ports, tie rods extending through said cylinder and securing the heads in position thereon, said tie rods being threaded at predetermined oints thereon, a conical defiector disposed wlthin the cylinder and having an annular liange formed on the flared portion thereof through which said tie rods extend, the apex of said conical delector being disposed immediately adjacent the inlet port and the outer peripheryof the aforesaid flange on said. deflector being slightl spaced from the inner Vwall ofv said cylin er, an additional deflect-or member of concavo-convex design disposed within the cylinder adjacent the out-let port thereof, said latter deflect-or also having an annular flange thereon through which said tie rods extend and arranged to dispose the concaved portion of the same toward the outlet of the cylinder, the peripheral edge of said concavo-convex deflector being also spaced from the inner wall of said cylinder, an intermediate deilector 'plate of circular design having a central slot therein, the aforesaid tie rods extending through said latter plate and the peripheral edge of said plate being disposed in contact with the inner wall of said cylinder and means engaging the threaded portions of said tie rods and said deflector members to removably and adjustably secure the latter to the former at the predetermined points thereon.

In testimony whereof I hereunto aliix my signature in the presence of two witnesses.
